Where does it say that the fast-hybrid AF works on,say, the Nex-6?

The point is, if Sony is only going to produce FE lenses going forward, it'd be nice to be able to use them effectively on existing cameras. Maybe that would be a problem with APS-C lenses too? If it requires a FW update for every new lens, that's a pain, and Sony is less likely to do that for older cameras. It's a weakness in the e-mount.

It is not plausible to think that FE lenses won't work with PDAF AF on APS-C bodies. My APS-C 35mm f/1.8 for instance works fine with PDAF with my A7.

I think it is a big part of Sony's strategy that FE lenses must be attractive on APS-C bodies as well.

APS-C lenses should be attractive on APS-C bodies, but yet Sony requires a FW update for PDAF to work. (I applied this FW update on my Nex-6 already.) They have a short list of lenses that were part of that update. Next week, they could come out with a lens -- either APS-C or FE -- and PDAF wouldn't be supported (probably).

For example both 35mm and 55mm FE lenses have a great FOV on APS-C bodies. The FE 70-200mm is great on APS-C as well. Only ultra wide and standard FE zooms are probably not a great idea on APS-C bodies, but here we are talking about 2-3 lenses.

To me that sounds like a paranoid assumption.

It was perfectly understandably when some lenses had to be firmware updated to support a brand new PDAF technology. Yes down the line there may be a new tech, but that is not only a problem for Sony cameras. For now most E lenses and ALL FE lenses support PDAF and will work with PDAF with all OS-PDAF bodies.

What is the problem really, or are we creating a new one?
